ABB IMHSS03  液压伺服模块

IMHSS03液压伺服模块是INFI 90⑧系统中用于控制涡轮机转速的阀门位置控制模块。它将伺服阀或I/H转换器连接到IMMFP01、IMMFP02或IMMFPO3多功能处理器模块。多功能处理器(MFP) 模块通过向液压伺服 (HSS) 模块发送位置要求来控制蒸汽或燃气轮机节流阀的位置。HSS 模块驱动其输出以打开或关闭节流阀，以满足位置需求。多功能数码复合机模块使用IMFCS01频率计数器模块来测量涡轮机转速。频率计数器模块通过计算和定时来自涡轮轴上磁性拾音器的脉冲来测量涡轮速度。多功能数码复合机模块使用此计数来计算涡轮机转速，并根据设定点计算新需求。该应用说明了 PLC 用户开始采用基于 PLC 的控制系统架构是多么简单，”ABB 自动化产品部机械控制和自动化产品经理 Knud Jansen 说。“NTK 的关键驱动因素是使用高级结构化文本语言进行编程的能力，以及强大的代码分析器工具——这为公司的软件开发人员在开发和测试 PLC 代码模块时提供了即时反馈。”

The IMHSS03 hydraulic servo module is a valve position control module used to control turbine speed in the INFI 90 ⑧ system. It connects the servo valve or I/H converter to the IMMFP01, IMMFP02, or IMMFPO3 multifunctional processor module. The Multifunctional Processor (MFP) module controls the position of steam or gas turbine throttle valves by sending position requirements to the Hydraulic Servo (HSS) module. The HSS module drives its output to open or close the throttle valve to meet position requirements. The multifunctional digital composite machine module uses the IMFCS01 frequency counter module to measure turbine speed. The frequency counter module measures turbine speed by calculating and timing pulses from the magnetic pickup on the turbine shaft. The multi-functional digital composite machine module uses this count to calculate the turbine speed and calculates new requirements based on the set point. This application demonstrates how simple it is for PLC users to start adopting a PLC based control system architecture, "said Knud Jansen, Mechanical Control and Automation Product Manager, ABB Automation Products. The key driving factors of NTK are the ability to program using advanced structured text languages, as well as powerful code analyzer tools - which provide immediate feedback for the company's software developers when developing and testing PLC code modules
